Electrochemical removal of polystyrene nanoplastics in a filter-press reactor using modified Ti-felt anodes: comparison of flow-through and flow-by configurations
[EN] Ti-felt anodes with high surface area were used as supports for Pt and SnO₂–Sb–Pt electrocatalysts. The anodes were tested in a filter-press electrochemical reactor for the electrooxidation of polystyrene nanoplastics (NPs) at an initial concentration of 100 mg·L⁻¹. Two reactor configurations w...

The anodes were tested in a filter-press electrochemical reactor for the electrooxidation of polystyrene nanoplastics (NPs) at an initial concentration of 100 mg·L⁻¹. Two reactor configurations were evaluated. In the first one (flow-through, F–T), the NP suspension was forced through the porous anode, which acted as a permeable electrode, enhancing contact between the NPs and both the anode surface and the oxidizing species generated in situ. In the second configuration (flow-by, F–B), the NP suspension flowed parallel to the anode surface. At 25 mA·cm⁻², the flow-through configuration substantially outperformed the flow-by configuration. For the Ti–Pt anode, F–T reduced energy consumption by approximately 7-fold and treatment time by about 15-fold relative to F–B. For the Ti–SnO₂–Sb–Pt anode, the corresponding reductions were ~6.5-fold in energy consumption and ~13-fold in treatment time. The influence of current density (50, 25, 12.5, and 5 mA·cm⁻²) was also investigated. For the Ti–Pt electrode operating in the F–T mode at 25 mA·cm⁻², a treatment time of only 40 min was achieved, with a Faradaic efficiency of 62.09% and an electrochemical energy per order (EEO) of 21.91 kW·h·m⁻³·order⁻¹. In contrast, under the F–B configuration at the same current density, the treatment time increased to 600 min, with a Faradaic efficiency of 8.27% and an EEO of 156.57 kW·h·m⁻³·order⁻¹.This research is part of the Spanish R+D+i contract TED2021-130905B-I00 funded by MCIN/AEI /10.13039/501100011033 and by the European Union NextGenerationEU/PRTR as well as the Red E3Tech Plus: Proyecto Redes de Investigación de la AEI Network E3Tech PLUS (RED2022-134552-T) project.
